\r十二经脉起止图\pt13a55.bmp\r
人身正脉，十有二经。每于平旦寅时，营气始于中焦，上注手太阴肺经，自胸中而出于中
府，至于少商，以次行于手阳明大肠等十二经，终于足厥阴肝经，而复始于太阴之肺也。凡手
之三阴，从脏走手；手之三阳，从手走头。足之三阳，从头走足；足之三阴，从足走腹。周流不
息，如环无端。前三图者，诵后十二经营行次序逆顺歌，则其首尾一贯，按图可悉矣。
肺大胃脾心小肠，膀肾包焦胆肝续。手阴藏手阳手头，足阴足腹阳头足。（此脏腑相传之序，及上
下所行之次也。）
（出十四经发挥。）
十二经络，始于手太阴，其支者，从腕后出次指端，而交于手阳明。手阳明之支者，从
缺盆上挟口鼻，而交于足阳明。足阳明之支者，从跗上出大指端而交于足太阴。足太阴之
支者，从胃别上膈，注心中，而交于手少阴。手少阴无支者，直自本经少冲穴而交于手太
阳。手太阳之支者，别颊上至目内 ，而交于足太阳。足太阳之支者，从 内左右别下合
中，下至小指外侧端，而交于足少阴。足少阴之支者，从肺出注胸中，而交于手厥阴。手
厥阴之支者，从掌中循小指次指出其端，而交于手少阳。手少阳之支者，从耳后出至目锐
，而交于足少阳。足少阳之支者，从跗上入大指爪甲出三毛，而交于足厥阴。足厥阴之
支者，从肝别贯膈，上注肺，入喉咙之后，上额循巅，行督脉，络阴器，过毛中，行任脉，入缺
盆，下注肺中而复交于手太阴也。
十二经脉起止图
人体主要的正经共有十二条。每天清晨寅时，营气从中焦开始运行，向上注入手太阴肺经，从胸中的中府穴出发，到达少商穴，然后依次流注于手阳明大肠经等十二条经脉，最终到达足厥阴肝经，再重新起始于手太阴肺经。凡是手的三条阴经，都是从内脏走向手指；手的三条阳经，都是从手指走向头部。足的三条阳经，都是从头部走向足部；足的三条阴经，都是从足部走向腹部。气血循环流动不停息，如同圆环一样没有起点和终点。前面三幅图，只要诵读后面关于十二经脉运行次序顺逆的歌诀，就能明白其首尾相连、一贯相通的道理，对照图表即可详尽了解。
肺经、大肠经、胃经、脾经、心经、小肠经、膀胱经、肾经、心包经、三焦经、胆经、肝经依次接续。手部的阴经联系内脏并走向手部，手部的阳经联系手部并走向头部；足部的阴经联系足部并走向腹部，足部的阳经联系头部并走向足部。（这是脏腑相传的次序，以及上下运行的顺序。）
（出自《十四经发挥》）
十二经络，起始于手太阴肺经，其分支从手腕后方出于食指末端，交接于手阳明大肠经。手阳明大肠经的分支，从缺盆上行挟持口鼻两侧，交接于足阳明胃经。足阳明胃经的分支，从足背出于大脚趾末端，交接于足太阴脾经。足太阴脾经的分支，从胃部别出上行穿过膈肌，注入心中，交接于手少阴心经。手少阴心经没有分支，直接自本经的少冲穴交接于手太阳小肠经。手太阳小肠经的分支，从面颊部分出上行至内眼角，交接于足太阳膀胱经。足太阳膀胱经的分支，从目内眦左右别出向下汇合于项部，下行至小脚趾外侧端，交接于足少阴肾经。足少阴肾经的分支，从肺部出来注入胸中，交接于手厥阴心包经。手厥阴心包经的分支，从掌心中沿小指与无名指之间出于其末端，交接于手少阳三焦经。手少阳三焦经的分支，从耳后出于外眼角，交接于足少阳胆经。足少阳胆经的分支，从足背进入大脚趾指甲丛毛处，交接于足厥阴肝经。足厥阴肝经的分支，从肝脏别出贯穿膈肌，上行注入肺脏，进入喉咙后方，上达前额沿头顶而行，行于督脉，联络生殖器，经过阴毛处，行于任脉，进入缺盆，下行注入肺中，从而再次交接于手太阴肺经。
Twelve Meridians Origin and Termination Diagram
The main regular meridians of the human body number twelve. At dawn during the Yin hour, Ying Qi (Nutritive Qi) begins in the Middle Jiao (Middle Burner), flows upward into the Lung Meridian of Hand-Taiyin, emerges from the Zhongfu (LU-1) point in the chest, reaches the Shaoshang (LU-11) point, and then sequentially circulates through the Large Intestine Meridian of Hand-Yangming and the other ten meridians, finally arriving at the Liver Meridian of Foot-Jueyin, before restarting at the Lung Meridian of Hand-Taiyin. All three Yin meridians of the hand travel from the Zang organs to the hands; all three Yang meridians of the hand travel from the hands to the head. All three Yang meridians of the foot travel from the head to the feet; all three Yin meridians of the foot travel from the feet to the abdomen. This circulation is unceasing, like a ring without beginning or end. Regarding the previous three diagrams, by reciting the following song on the sequence and direction of the Twelve Regular Meridians, one can understand their continuous connection from start to finish and examine them thoroughly via the charts.
Lung, Large Intestine, Stomach, Spleen, Heart, Small Intestine, Bladder, Kidney, Pericardium, Sanjiao (Triple Energizer), Gallbladder, Liver follow in succession. Hand Yin meridians connect to Zang organs and go to the hands; Hand Yang meridians connect to the hands and go to the head; Foot Yin meridians connect to the feet and go to the abdomen; Foot Yang meridians connect to the head and go to the feet. (This describes the order of transmission among Zang-Fu organs and the sequence of movement up and down.)
(From *Fa Hui of the Fourteen Meridians*)
The Twelve Meridians begin with the Lung Meridian of Hand-Taiyin. Its branch emerges from behind the wrist to the tip of the index finger, connecting to the Large Intestine Meridian of Hand-Yangming. The branch of the Large Intestine Meridian of Hand-Yangming ascends from the Quepen (LI-15) point, flanking the mouth and nose, connecting to the Stomach Meridian of Foot-Yangming. The branch of the Stomach Meridian of Foot-Yangming emerges from the dorsum of the foot to the tip of the great toe, connecting to the Spleen Meridian of Foot-Taiyin. The branch of the Spleen Meridian of Foot-Taiyin diverges from the stomach, ascends through the diaphragm, and pours into the heart, connecting to the Heart Meridian of Hand-Shaoyin. The Heart Meridian of Hand-Shaoyin has no branch; it proceeds directly from its own Shaochong (HT-9) point to connect with the Small Intestine Meridian of Hand-Taiyang. The branch of the Small Intestine Meridian of Hand-Taiyang diverges from the cheek, ascends to the inner canthus of the eye, and connects to the Bladder Meridian of Foot-Taiyang. The branch of the Bladder Meridian of Foot-Taiyang diverges left and right from the inner canthus, descends and converges in the nape region, travels down to the lateral side of the little toe, and connects to the Kidney Meridian of Foot-Shaoyin. The branch of the Kidney Meridian of Foot-Shaoyin emerges from the lung, pours into the chest, and connects to the Pericardium Meridian of Hand-Jueyin. The branch of the Pericardium Meridian of Hand-Jueyin follows from the palm along between the little and ring fingers to emerge at their tips, connecting to the Sanjiao Meridian of Hand-Shaoyang. The branch of the Sanjiao Meridian of Hand-Shaoyang emerges from behind the ear to the outer canthus of the eye, connecting to the Gallbladder Meridian of Foot-Shaoyang. The branch of the Gallbladder Meridian of Foot-Shaoyang enters from the dorsum of the foot into the nail bed and hair tuft of the great toe, connecting to the Liver Meridian of Foot-Jueyin. The branch of the Liver Meridian of Foot-Jueyin diverges from the liver, penetrates the diaphragm, ascends to pour into the lung, enters the throat posteriorly, ascends to the forehead, follows the vertex, runs along the Du Mai (Governing Vessel), connects to the genitalia, passes through the pubic hair region, runs along the Ren Mai (Conception Vessel), enters the Quepen (ST-12) area, descends to pour into the lung, and thereby reconnects with the Lung Meridian of Hand-Taiyin.
